concern.' l Be it knownV that I, DAVID G. DE Miur, residing at Tampa, inthe county of'Hillsborough and State of Florida, have invented certainnew and useful Improvements in Ball-Cocks, of which the'following is aspecification, referdrawings.

This invention relates to ball cocks, and more particularl v to aneicient valve mechanism for flushing tanks.

The object of my invention is to simplify v a valve device or ball cock,yegadproduce a highly efficient and positivey m anism which will give agreat amount of satisfaction' and will last a'. long time.

invention consists' of .certain novel construcclained. l

and aivotally mounted at 11, in the aperture 12 o the frame 6, is aweighted catch 13,t'hat has its inner end 14 normally overhanging theannular flange 10, so that if the lever arm 15 should become detached,at 16, from the parallel lugs 17, integral with the closed top of thelunger casing 9, the catch 13 will by the annular flange 10 and prevent'any y great a flow of water through the auxiliary extension 7 andthence around the passage fhrmed by the spiral or .threaded portion 8o'n the outer face ofvauxiliary extension 7. Between the closed to ofplunger casin 9 cip the auxiliary hol ow extension is placed the washer17, which produces a tight closure, ordinary. risen in tank 1 to causethe'rod 18 to assume' al horizontal position, a very tight closure isleakage or seepage out of pipe 7 after the water has risen to itsApredetermined level in the tank. To permit a tight closure of pIungercasing 9 upon the hollow extension ,I arrange a vent pipe 19 in the tank1 having the lower end of pipe 19, at 20, threaded into tureformed inthe plunger 'casing 9 near the top, so as to vent the interior of theplunger tension 7 to its normal Fig. 1.

The lever arm 15vis seated position,

pivotally mounted, by upon the parallel extensions ,22 formed at theupper end of frame 6. Further, I use cotter pins for all of theconnections, `hotter pin 23 being positioned in registering apertures inthe parallel ears inte al with the clamping l body 25 surrounds the ballfloat carrylngirod 18, by formin on the H oat carrying ro 18, aplurality `o cotterpin receiving notches 26, which notchesl registerwith the apertures in the aral el ears 24; when the cotter pin 23 is paced in these apertures end registering notches, fixed position,
